For deeper flavor, apply the rub and refrigerate the ribs overnight; bring closer to room temp before grilling. Baby back ribs cook a bit faster—start checking 15–20 minutes early. Foil-wrapping during part of the cook can make ribs extra moist (at the expense of a firmer bark). Leftovers: Refrigerate up to 4 days; reheat at 300°F for about 15 minutes. Freeze tightly wrapped up to 3 months.
